iefeiing to Fig. l ofhe drzwving's5 which *line rzvtei one foim of my invention, A fiesby means of two adapter sleeves C 'ned iii operative position Within a lhousi'A ood e connecting element D 'tha joins'said,

adiipei* eieeves together. The adeper Sieeves C are momieci on the shaft i inside of 'the inner rece members l of the beaiiiigs, and

the foimec'tiiig; eiemen D is arranged bei iidzipei' sleeves and is connect-ed o eamo by of mtemei sciew threads g3 Leve 3 on the connecting element D that copcrate with external screw threads 4f on the inner end portions of the adapter sleeves, the Connecting element D being of tubular form and arranged longitudinally of the shaft A, so that the end portions ot same surround the inner end portions ot the adapter sleeves C. ln the torni ot my invention shown in Fig. l the outer surfaces of the adapter sleeves are tapered and the bores in the inner race members l oit the bearings through which said adapter sleeves pass are also tapered, thereby permitting; the bearing members to be locked securely in position by rotating the adapter sleeves in such a direction that they Will be screwed inwardly into the connecting element D, causing the inner race members l to be clamped securely to the adapter sleeves C. T he connecting element D is preferably so proportioned that the ends ot same'bear against the inner` race members l of the bearings and hold said inner race members spaced apart and out of contact with the side Walls of the portions 5 of the housing B in which the bearings are mounted, and holes 6 are preferably formed in the outer ends of the adapter sleeves, as shown in Fig'. 8, so as to permit the adapter sleeves to be tightened With spanner Wrenches. in the mounting illustrated in l each adapter' sleeve C is split longitudinally, as shown in Fig. 3, and is provided with a screw l' that is adapted to be tightened so as 'to connect said sleeve securely to the shaft A. Each adapter sleeve is also provided with a. set screw or similar device 8 lthat is adapted to be screwed inwardly into engagement with the shaft A, so as to prevent the sleeve trom backing Oior't-he entire mounting from slippingr endwise.

In installing the device the adapter sleeves C are screwed intothe master sleeve or connecting element D, using two Spanner wrenches tor this purpose. llhen the adapter sleeves cease turning); on the shaft A, the operation ot installing` the device is complete, except for tightening the lock screws 7, used to draw the adapter sleeves together, and tightening; the set screws 8, used to prevent the adapter sleeves from backing ott and to prevent end slippageot the entire mounting. lfVhen the adapter sleeves cease turning on the shaft Without undue tension being exerted on the Spanner Wrenches, the entire mounting is firmly held in place for all practical purposes, and no undue outward strain is plaoel upon the* inner race members ot the bearings, thus eliminating the possibilitykor" the bearings being injured, as so often occurs in the operation of tightening the ada'oter sleeves. oit anti-friction bearing mountings of the hind now in general use. With improved" bearing mounting it is practically impossible to subje'et the inner .rece members oit-the bearings to undue strains when the adapter, sleeves are tightened with Spanner Wrenches, and lfurthermore, my improved mounting can be installed by an inexperienced person, thereby overcoming the necessity` ot employing a high-priced mechanic or millvvright to install the moi'lnting. My improved mountu ing is adapted to be used with ball bearings or roller bearings, it is so designed that it insures the posit we locking together of the component parts of the entire mountingn Without. havingl to depend upon the outer housing E or the. removable end caps 5a ot said housing to lock the piits together.

Still another desirable feature of such a bearingr mounting,T is that it can be used successtully on very long shafts, due to the tact that it is so designed that the bearings are not subjected to'end thrusts troznthe shaft. f l'n order to compensate for shaft dei'lection and vibration, housing B with a substantially cylindricalshaped portion 9 that is rochably mountedr in the supporting structure that carries the housing B, said supporting structure being ot any preferred torni, so long; as it is so designed that it permits the housing B to4 rock slightly, and thus compensate for de iiection or vibration ot the shaft A. lathe torni ot my invention shown in Figi. l the supporting structure tor the housing?) comu prises shoes l() having eoncaved surtaees that conform to the convened portion 9 on t-hehoiipg B, said shoes being combined with suspensioi'rbolts 12, so `as to provide a practically universal lioint between the moimtinp,- and the supporting structure that calf-ries the mounting,

Any preferred means can be used toa preventing' the master sleeve or connecting elementi) from rotating` during the operation otn tighteninethe adaptersleeves C, the means that l prete-r to use 'tor this purpose consisting:m orl a screw 13 shown in Fig. 2 that l prefer to provide the' is adapted to be screwed 'into internally screw-threaded opening in the sleeve B tar enough to cause the inner end portion oi said serevv 13 to enter a hole ist in the master sleeve D.- After the adapter sleeves have been properly adjusted the screw i3 is removed troni the housing Band turned end :for end so that the short screw threaded portion i3 on said screvvcan be screwed into the internally the housing B, the screivli thenaeting as a dust plug that prevents dirt and the like from entering the housing B ln Fig. el ot the drawing-s l have shown :my improved mounting, used with a pulley which may be eithera loose pulley, a friction clutch pulley, a mule pulley, an idler pulley, or a tightener pulley.l The various parts of the mounting are substantially they 1 l same as the parts of the mounting sho-Wn 1n screw-threaded hole in :newest f l. with the exception that the hub ly or' the pulley is used in place of the housing to carry the outer race members 2 of the bearings.

lin F 5 of the drawings l have illustrated an anti-friction beauringn mounting constructed in accordance with i'ny invention, such as can be used when it is possible to control toe size ot' the shaft, rod pin or gudgeon upon which the mounting is installed and which has a j )ractically air or piston fit with the bore oiE the adapter sleeves C. In this forni ot my invention each of the adapter sleeves C consists of a non-split sleeve having a straight cylindrical `portion 'that [its in straight? cylindrical bore in the inner race. member l `of the bearing' with which it cooperates, the adapter sleeves C being so constructed that the flanges l5 on the outer ends oif saine bear against the inner race members l of the Jearinqsa and thus clamp said inner race members; securely against the ends one. the master sleeve or connecting element D.

An anti-friction bearing mounting of the construction above described overcomes a. serious defect ot' bearing` inountings of the liind now in use that are equipped with adapted .sleevesg owingJ to the fact that it permits the adapter sleeves to be tightened without liability of subjecting the bearing` members to undue strains; it comprises only a few parts of simple design, thus permitting 4it to be manufactured at a lonY cost; it :an be easilv installed by an unskilled per son; it insdres ,concentric arrangement of the bearings and the shaft, thus eliminating vibration. due to eccentric bearing mount ings; it is selflalining so lthat it automatically compensates for shaft dellection and vibration; it is of such design that the bearin s will not be subected to end thrusts 'thus compensating for contraction and e2;- pansion of the shaft, due to changes in teni-- perature; it can be used with. various makes of ball bearings and roller bearings and can bc applied easily to 'various kinds ot supporting; trames, stands oir brackets, and as it has provision for supporting tivo bearings, it provides sufficient bearing` capacity tor Athe shaft Without resorting to a heavy duty antidrgction bearing.
